10-19-2006 · EurekAlert!

The need to eat is triggered by the hormone ghrelin.

A new study shows that in mice and rats, ghrelin triggers the same neurons as delicious food, sexual experience, and many recreational drugs; that is, neurons that provide the sensation of pleasure and the expectation of reward.
